hello
this question has been teasing me 4 a long time
faraday's law states that when mag flux thru a coil changes it induces an emf in it..
the magnitude of which is equal to the rate of change of flux
now for an 'n' turn coil e= - n.d(phi)/dt -----this expression is given in all textbooks
the question is:-
is it possible that emf can be INDUCED(i emphasize INDUCED)by only changing the number of turns of the coil thereby changing flux linkage of the coil.
more over can emf be induced in open (or not necessarily closed) circuits???
thank u
